Maintenance Man fatality at shamrock (ACG Materials), TX, April 27, 2013

Employee was cleaning a jammed rock from a return roller on a track mounted CEC Crusher. The engine was still running and the belt was engaged. Employee "assumed" belt was turned off because the head pulley was not spinning skipping on the belt; the belt was actually stalled. He did not lock out/ and tag the crusher before performing the work to de-energize all power.

1. Management failed to ensure that persons followed previously established procedures to deenergize the crusher before performing maintenance work. Additionally, the discharge belt conveyor was not blocked against hazardous motion.

   Corrective action: Management retrained all miners regarding established procedures to deenergize the mobile crusher and block moving machine parts against hazardous motion before maintenance work begins.

Findings from MSHA's final investigation report, which supersedes the preliminary narrative above.
